OPERATION

HOW THE MACHINE WORKS

The steering wheel controls the direction of machine travel. The directional pedal controls the speed and forward/reverse direction. The brake pedal slows and stops the machine.

The side brush sweeps debris into the path of the main brush. The main brush sweeps debris from the floor into the hopper. The vacuum system pulls dust and air through the hopper and the dust control system.

When sweeping is finished, shake the dust filter and empty the hopper.

BRUSH INFORMATION

For best results, use the correct brush type for the cleaning application.

NOTE: The amount and type of soilage play an

important role in determining the type of brushes to use. Contact a Tennant representative for specific recommendations.

WHILE OPERATING THE MACHINE

Pick up oversized debris before sweeping. Pick up wire, string, twine, large pieces of wood, or any other debris that could become wrapped around or tangled in the brushes.

NOTE: Debris can be placed in the hopper through the hopper access door on the front of the hopper.

Drive as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine. Overlap the sweep paths by several centimeters (a few inches).

Avoid turning the steering wheel too sharply when the machine is in motion. The machine is very responsive to the movement of the steering wheel.

Avoid sudden turns, except in emergencies.

Adjust the machine speed and brush pressure.

Use the lowest brush pressure for best performance.

Keep the machine moving to prevent damaging floor finishes.

If poor cleaning performance is observed, stop cleaning and refer to MACHINE

TROUBLESHOOTING in this manual.

Perform the Daily Maintenance Procedures after each use (see MACHINE MAINTENANCE in this manual).

Drive the machine slowly on inclines. Use the brake pedal to control machine speed on descending inclines. Sweep with the machine up inclines rather than down inclines.

FOR SAFETY: When using machine, go slowly on inclines and slippery surfaces. Do not sweep on ramp inclines that exceed 14% grade or transport (GVWR) on ramp inclines that exceed 17.6% grade.

Do not operate machine in areas where the ambient temperature is above 43_ C (110_ F). Do not operate sweeping functions in areas where the ambient temperature is below freezing 0_ C

MAINTENANCE

ENGINE


COOLING SYSTEM

FOR SAFETY: When servicing machine, avoid contact with hot engine coolant. Do not remove cap from radiator when engine is hot.

Allow engine to cool.

Check the radiator coolant level daily. Refer to the coolant manufacturer for water/coolant mixing instructions.

Check the radiator core exterior and hydraulic cooler fins for debris daily. Blow or rinse (with low pressure air or water) all dust through the grill and radiator fins, the opposite direction of normal air flow. Be careful to not bend the cooling fins when cleaning. Clean thoroughly to prevent the fins from becoming encrusted with dust. To avoid cracking the radiator, allow the radiator and cooler fins to cool before cleaning.

Flush the radiator and the cooling system after every 800 hours of operation.

Check the radiator hoses and clamps after every

200 hours of operation. Tighten loose clamps.

Replace damaged hoses and clamps.

FOR SAFETY: When servicing machine, avoid moving parts. Do not wear loose clothing or jewelry.

MAINTENANCE

To remove the filter element, raise the hopper and engage the hopper support bar. Set the parking brake and turn the engine off. Remove the top two dust skirt clips and pull back the dust skirt to access the air filter housing.

AIR FILTER


The engine air filter housing is located in front of the engine compartment under the lintel.

Replace the air filter element when the air filter indicator shows restriction in the air intake system or the filter element is damaged. Refer to AIR

FILTER INDICATOR.



Remove the filter element. Carefully clean the end cap and the interior of the housing with a damp cloth. Clean the housing sealing surfaces.

S20 Diesel 9006712 (4−2014)

41

MAINTENANCE

Install the filter element into the air filter housing and reinstall the dust cap with the water drain pointing down.

ENGINE BELT

Check the engine belt tension after every 100 hours of operation. Adjust tension as necessary.

Proper belt tension is 12 mm (0.5 in) from a force of 4.5 kg (10 lb) applied at the mid-point of the longest span.

Push the reset button on the end of the indicator to reset the air filter indicator after replacing the air filter element.

08935

WARNING: Moving belt and fan. Keep away.

VALVE CLEARANCE

Check and adjust the valve clearance to 0.145 to

0.185 mm (0.0057 to 0.0072 in) while the engine is cold after every 800 hours of operation.

FUEL FILTER

The fuel filter traps fuel contaminants. The filter is located on the fuel line near the fuel pump.

FOR SAFETY: When servicing machine, keep flames and sparks away from fuel system service area. Keep area well ventilated.

Replace the fuel filter after every 800 hours of operation.

42

S20 Diesel 9006712 (1−2015)

FUEL LINES

Check the fuel lines every 50 hours of operation.

If the clamp band is loose, apply oil to the screw of the band and securely tighten the band.

MAINTENANCE

PRIMING THE FUEL SYSTEM

Typical diesel fuel systems require priming to remove pockets of air from the fuel lines and fuel components. This is usually required after running out of fuel, changing fuel filter elements or repairing a fuel system component. Air in the fuel prevents smooth engine operation.

This fuel system however is self-priming. The return line comes from the top of the injector that allows the air to escape through the return line.

VACUUM FAN BELT

Check the vacuum fan belt tension and wear after every 200 hours of operation. The correct tension is when the belt deflects 4 mm (0.16 in) from a force of 0.7 kg (1.5 lb) at belt midpoint.

The rubber fuel lines can become worn−out whether the engine has been used much or not.

Replace the fuel lines and clamp bands every two years.

FOR SAFETY: When servicing machine, keep flames and sparks away from fuel system service area. Keep area well ventilated.

If the fuel lines and clamp bands are found worn or damaged before two years’ time; replace or repair them at once. Bleed the fuel system after replacement of any fuel lines, see PRIMING THE

FUEL SYSTEM. When the fuel lines are not installed, plug both ends with clean cloth or paper to prevent dirt from entering the lines. Dirt in the lines can cause fuel injection pump malfunction.

BATTERY

Clean and tighten the battery connections after the first 50 hours of operation and after every 800 hours after that. Do not remove the vent plugs from the battery or add water to the battery.
